This is certainly an improvement, though I have a few quick issues to call out:

• When designing the silhouettes of your additional masses, be careful about where you put sharp corners - remember that this form of complexity, along with inward curves, can only occur when the mass presses up against a defined structure, and they cannot occur arbitrarily.

• Don't cut off any additional masses where they're overlapped by any others - be sure to draw each one in its entirety, and remember that when you add a mass to your construction, it becomes part of the existing structure, and so any forms you add next wrap around them as well.

• When it comes to feet, hooves, etc. the use of "boxy" forms - that is, putting corners in the shape that actually imply the presence of separate planes/edges, making the form look more 3D - is very useful. With hooves it's generally just the one form, but with paws and such, we can build up a boxy base and then each toe as shown here on another student's work.

I've demonstrated all three of these points here.

The last thing I wanted to call out is that when you draw your eyes, it can help to construct each lid as its own additional mass, wrapping them around the eyeball structure as shown here. Continuing to think constructionally and in 3D when drawing them is worthwhile.

Anyway, I think these are all points you can continue to work on in your own practice, and overall you've moved very much in the right direction. I'll go ahead and mark this lesson as complete.
